Methyl iodide → Methyl 4-benzylthionicotinate

Participants

Reaction Steps

A suspension of 2.45 g (0.01 mole) of 4-benzylthionicotinic acid in 35 mL of dry acetonitrile was treated with 1.52 g (0.01 mole) of 1,8-diazabicyclo[5,4,0]under-7-ene (DBU). 1.7 g (0.01 mole) of methyl iodide was added and stirring was continued for 7 hours. The reaction was carefully diluted with water to crystallize 430 mg of methyl 4-benzylthionicotinate which melted at 98°-99° C.
